These social accounts are the company’s social accounts that will appear in the footer of the front end, and which site site visitors can click on to follow the company on social media. If you want to turn off any of the social networks, just leave the value blank. Also note that you do not enter the entire url of your social account. Just the name is fine, as the application automatically adds the base url of the social network.
contact email is very necessary. This is the email address that emails sent via the contact form will be sent to. So Please make sure this is set.
